Arterial Management > Enforcement > Speed Enforcement


Automated enforcement technologies can assist with the enforcement of speed limit compliance. Still or video cameras, activated by detectors, can record vehicles traveling faster than the speed limit.


NYC Automated Speed Enforcement pilot sees a 14 percent decline in the overall number of people injured in crashes in school zones where speed cameras were activated.(06/01/2017)

Speed enforcement cameras can reduce injury crashes by 20 percent.(01/05/2014)

Speeding has dropped 65 percent in Chicago neighborhoods where Automated Speed Enforcement systems have been installed.(11/19/2013)

Speed camera programs can reduce crashes by 9 to 51 percent. (September 2007)

Controlled motorways offer improved travel time reliability and less stress for drivers, but in some cases costs can outweigh benefits.(November 2004)

Automated speed and red light enforcement lowered crash frequency by 14 percent, decreased crash injuries by 19 to 98 percent, and fatalities 7 to 83 percent.(2001)

Automated enforcement systems have reduced red-light violations by 20 to 60 percent and crashes by 22 to 51 percent. (June 1998)

Automated speed enforcement systems have reduced speed by 10 percent, decreased all crash injuries by 20 percent, and reduced serious and fatal crash injuries by 50 percent. (March 1995)
